In response to Re: pipes knocking
It is probably not a new thing, it is just that the plastic pipes could expand slightly and absorb the sound. You must have fast closing faucets and when you turn them off quickly it creates a "water hammer". There are several ways to treat it, but which one or combination of several is best for your situation would require an on site evaluation to see exactly what is causing it. It could also be due to some of the new lines not being secured properly and the shutoff pressures cause them to move and bang against the interior of the wall or ceiling.
: Due to inferior pcv pipes, I recently had my inside pipes replaced with copper pipes. Now everytime I turn off the water anywhere in the house I hear a knocking sound. Should I be concerned?

: Thanks.
